Hi, within my job i use industrial GSM routers (a GSM modem with thernet port) to connect computers on site to the internet and as far as my understanding of them, there a router with a simcard and act like any other router?

So..i have my ethernet shield on my arduino and i have set it to connect to a server i have, this works fine when i share my computers ethernet port and loop the arduino into there (so its using my internet) when i plug it into the GSM router however, it cannot make a connection, yet throws no ethernet connection errors.
